首先，我先将图片通过wx.downloadFile下载到本地中，然后在通过wx.saveFile进行本地缓存，打印出的缓存地址通过小程序开发者工具可以直接打开并显示，但是image的binderror报错(GET http://store/2AhRbFtOy0Bh7e76328a2866b2a5a76bb97a3e68e289.svg 404 (Not Found)),到底什么原因，求大佬解答。

    loadImg2: function (e) {
        const that = this;
        if (e == undefined) {
            e = this.data.category0[0]
        }
        wx.downloadFile({
            url: '在线的图片路径.svg',
            success: function (res) {
                const tempFilePath = res.tempFilePath;
                wx.saveFile({
                  tempFilePath: tempFilePath,
                  success: function(res) {
                    const savedFilePath = res.savedFilePath;
                    
                    that.setData({
                        imgUrl2: savedFilePath
                    }, function() {
                        console.log(that.data.imgUrl2);
                    });
                    
       
                  }
                });
            }
        })
    },
